Now, of course the initial RAM disk image is not on the encrypted

root file system, so anyone who would come and take the the whole

computer would have the Mandos client key when they took the server
53
offline and read the disk with their own tools. *But*, by then the
54
Mandos server will have detected that the original server is no
55
longer online and will no longer give out the encrypted key. The
56
timing here is the only real weak point, and the method, frequency
57
and timeout of checking can be adjusted to any desired level of

root file system, so anyone who would then have pyshical access,

could try to take the server offline and read the disk with their

Nope, the network stuff is all done over TLS, which provides

The default for the server is to use "fping", the replies to which
